It has the effects of anti-platelet aggregation, dilation of arterioles, and improvement of microcirculation. Animal experiment results show that this product is non-irritating, non-allergic, and non-hemolytic.

This product is an amide local anesthetic with a biphasic effect of excitation and inhibition on the central nervous system. At low doses, analgesia and drowsiness occur, and the pain threshold is increased. At high doses, the effect or toxicity is enhanced and it has an anticonvulsant effect. It has a regulatory effect on the electrical activity of myocardial cells and can reduce myocardial autonomy. At therapeutic doses, it has no significant effect on myocardial electrical activity, atrioventricular conduction, and contractility. However, at high blood concentrations, it may slow down the conduction velocity, cause atrioventricular conduction block, and inhibit myocardial contractility and cardiac output.

1. Antipyretic effect: inhibits fever caused by bacterial endotoxin, promotes fever to subside, and fights irritability caused by fever and other reasons. 2. Anti-inflammatory effect: fights against the increased capillary permeability caused by chemical irritants xylene and human inflammatory mediator histamine, and inhibits the development of inflammation. 3. Antiviral effect: occupies the DNA and protein binding sites during viral replication, prevents protein from encapsulating DNA fragments, and has an inactivation effect on adenovirus type 3, influenza virus type A1, type A3, respiratory syncytial virus, etc. 4. Antibacterial effect: has an inhibitory effect on Staphylococcus aureus, group A streptococcus, group B hemolytic streptococcus, pneumococcus, Escherichia coli, aerogenes, Klebsiella pneumoniae, Pseudomonas aeruginosa, Shigella flexneri and Candida albicans. 5. Promotes adrenal cortex function: has a significant effect on promoting adrenal cortex function.

Terbutaline sulfate is an adrenergic receptor agonist. It can selectively stimulate β2 receptors to relax bronchial smooth muscles, inhibit the release of endogenous spasm-causing substances and edema caused by endogenous mediators, improve the bronchial mucociliary clearance ability, and relax uterine smooth muscles.
